Now suppose 'val' is your value you want to decide upon, here's the code: [code] var rangeTable = [1,6, 0, // 1..6 -> 0 10,44,1, // 10..44 -> 1 88,100,2 ]; var val = 88; var decision=-1; for (var i=0;i<rangeTable.length;i+=3) { if ((val >= rangeTable[i]) && (val <= rangeTable[i+1])) { decision = rangeTable[i+2]; break; } } switch (decision) { case 0: // for range 1..6 break; case 1: // 10..44 break; case 2: // 88..100 break; } [/code] HTH -- Regards, [url=http://lgwm.org/]Elias[/url] Loading...
